老生常谈高频淬火炉原理再次给你讲解

高频淬火炉的原理：工件放到感应器内，感应器一般是输入中频或高频交流电 (1000-300000Hz或更高)的空心铜管。产生交变磁场在工件中产生出同频率的感应电流，这种感应电流在工件的分布是不均匀的，在表面强，而在内部很弱，到心部接近于0，利用这个集肤效应，可使工件表面迅速加热，在几秒钟内表面温度上升到800-1000?C，而心部温度升高很小

科學高頻淬火原理
將工件放在用空心銅管繞成的高頻爐感應器內，通入中頻或高頻交流電後，在工件表面形成同頻率的的感應電流，將零件表面或局部迅速加熱（幾秒鍾內即可升溫800～1000℃，心部仍接近室溫）若幹秒鍾後迅速立即噴(浸)水冷卻（或噴浸油冷卻)完成浸火工作，使工件表面或局部達到相應的硬度要求。高频淬火感应器

AN OLD SETTLER. AN OLD SETTLER. "Of course, you know where the Dutchman is to be found?" "I am afraid I was as foolish as that," Bruce said, with a faint smile. "That sort of people seem to know when one is under the weather. And there was one very plausible fellow who sent me a confidential letter. I fell into the trap, and if I can't find ￡500 tomorrow I am ruined." "I believe that it is my duty to take that task upon me, assisted by some well-known burgesses, who have undertaken to stand by me. 72 When people in Parisian society thought of the country, they thought of lambs with ribbons round their necks, shepherdesses in fanciful costumes with long crooks, or a “rosière” kneeling before the family and friends of the seigneur to be crowned with flowers and presented with a rose as the reward of virtue, in the presence of an admiring crowd of villagers; of conventional gardens, clipped trees, and artificial ruins; but wild, picturesque mountain scenery was their abhorrence. She must have tossed the life preserver from the stern. Nothing else explained its employment. From the air, to an observer who had no idea that his craft had been used, all should seem natural, Larry decided as he and Dick, with Sandy’s discarded garments, and with the caretaker ruefully grumbling, chose a place of concealment. She smiled. "The chances that she will marry are excellent." Arizona had its full share of murder and sudden death. But New Mexico had more than that. Spring passed on there, with warmth for the snow-wrapped mountains, and blistering heat for the dead plains, and her way was marked with lifeless and mutilated forms. Chapter 24 "Deer Bat: Got yore $100 all right, but doant send by that "Rose, marry me." "Unhappy woman!" said the monk, in a tone that seemed to encourage her to proceed—"what would you of me?" "Roland de Boteler, do you intend to submit?—but you have not a mother's feelings!" "These knaves wish to carry things with a strong hand, my liege," said the Earl of Oxford, bending his knee as he presented the scroll. HoME 手机看片1204免费人一级ENTER NUMBET 002jcqz.com.cn
